- Photographically Printed Sheets,

Be it known that I, CuAnLEs F.- PEAsE, a citizen of the United States,residing at Golumbus, in the county of Franklin and State of Ohio,haveinvented certain new and useful Improvements in Processes for Finishingof which the fol owing 1s a s ecificat'ion.

My invention re ates to a process for finish- I ingphotographically-printed sheets.

The invention-has for its more essential ohand drying continuous sheetsof blue- My purpose is'to use the process in connection with what isknown as a continuouslyprinting machine, although this is not essential.

Finall the invention contemplates a process whic will be simple andinexpensive to conduct and one which willnot re uire the use of exensive or complicated machinery.

In or er that my process may be clearly understood, Ihave devised anapparatus by 5 which the process may be carried out which I haveillustrated in. the accompanying drawings, wherem- Figure 1 is adiagrammatical end elevation.

of the apparatus. Fig. 2 is a front elevation; and Fig. 3 is a partialend elevation of the upper portion of the apparatus, showing a wipin 1device applied in lieu of the uppermost ro or.

I wish it to be understood that I have merely shown the apparatusillustrated in the drawin s as one form of the many apparatuses an(machines which might be employed. I

in carrying out my process in connection with the apparatus illustratedthe numeral 1 designates a roll of continuous photographic paper whichhas been properly printed and ready to be finished, or in lieu of thisroll the paper may be taken directly from the tinting-machine. The sheetof paper 2 is ed over a plurality of transverse rods 3, arranged in acurve over atrough 4, adapted to receive the washin -water, and arrangedso as to maintain the evel of the water in the trough at such a heightthat the sheet 2 will not at an time come in contact with the water,sheet dry. A guide-rode is arranged over tne rods said rods 3 and 5.After passing over the rods 3 the paper isled' upwardly overtranswringing, or wipthus eeping the back or rear side of the 3, and thepaper passes between the verse rods 6, arranged on an incline, at theback of which is arranged a guard-plate 7, which is formed-by continuingthe bottom wall of the trough 4 upwardly. The angle of inclination ofthe rods 6 and the guard-plates 7 is quite steep, so as to allow thefalling water a quick descent, and thus prevent the same fromsaturatingthe'sheetof paper, but acting merely to wash the same as thepaper is carried upward. A suitable water-spraying device 8 is located,above the rods 6 and intermcdiately of two transverse rollers 9, betweenwhich the paper is passed. The paper is passed over the front of thelower roller 9 and in back of the upper roller and the spraying devicearranged so that the water will be sprayed directly on the sheet ofpaper,

I and thus running or falling over the outer surface of the samedownwardly until it flows off each side of the sheet into the trough 4.The paper after being led back of the upper roller 9 is passed betweentwo suitably-supported wringingrolls l0, squeeze the water from thepaper, so as to reduce the paper from a wet to a moist condition. It isto beurfderstood that in lieu of one of the rollers 10 a suitable wipingdevice may be employed. In Fig. 3 I have shown a flat rubber strip 10,supported in a grooved bar 10*, so as to bear on the wet surface ol thepaper and wipe the superfluous water and moisture therefrom; The sheetof-paper after being passed between the rollers 10 or be .tween theroller 10 and the wiping-strip ll) is led horizontally across and abouta roller 11, with which it is held in contact by an endless tape 12,passing over an upper roller 13 and about oppositely-disposed rollers14. The paper is thus carried around by the tape on its outer surfacedownwardly across and upwardly to a delivering-roller l5, mounl edopposite the roller 11. Both the rollers i l and 15 are set slightlyinwardly, so as to iirmly engage with the tape l2, and thus keep theshoot of paper ta'ut. Adjacent the front vertical run of the tape Iarrange any heating device, such as ,a plurality of steam or hot-waterpipes 16, and in some cases it might be found convenient to arrange pi)es l7horizontally below the bottom run of the tape. It will be ap arentthat after the paperhas been once lec which wring or.

' paper, and finally drying the same, allsheet of paper is passingaround the tape 12 the heat generated either by the pipes 16 or 5 willbe sufficient to thoroughly dry the s eet.

While I have shown and described the above-mentioned apparatus, I wishit understood that the said apparatus forms no .special part of thisinvention; but the essential feature is the process of finishing photographically-printed paper b first carrying the paper upward againstalling water to wash t e same, then wringing or wipin the a continuousoperation. Photographicafl printed paper may in this way beexperfitiously and readily finished without the usual handling andlaborious methods now commonly employed. i

Having now fully described my invention, What I claim, and desire tosecure by Letters Patent, is

1. A process of finishing photographicallyprinted paper by a continuousoperation which consists in first moving the said paper in a drycondition upwardly and simultaneously wetting the printed surfacethereof and then drying the paper by artificial means.

2. The process of finishin sheets of photographically-printedpaper acontinuous operation which consists in dist moving the said sheets in adry condition upwardly and simultaneously exposing the printed surfacethereof to falling water and then drying the same by artificial means.

3. The process of finishin sheets of photographically-printed paper acontinuous operation which consists in first moving the dry sheetsupwardly and simultaneously exposing the printed surface thereof tofalling from the sheets and finally drying the said sheets by artificialmeans.

4. The process of finishin sheets of photographically-printed papery acontinuous operation which consists in first moving the dry sheetsupwardly and exposing only the I printed surface thereof to fallingwater, then removing the superfluous water from the sheets and finallydrying said sheets by art finial means.

5. The process of'finishing dry sheets of photographicallyprinted paperby a'con'tinuous operation which consists in Wetting only the printedsurface of the same and drying the sheets by artificial means.

6. The process of finishing dry sheets of photdgraphically-printed paperby a con tinu ous operation which consists in Wetting only the printedsurface of the same, then rernow ing superfluous water from the sheetsand finally drying the said sheets by artificiai means.

In testimony whereof I affix my signature in presence of two Witnesses.
